Error attaching icon when sending notify-send to Linux from Pycharm

Question

I want to send notify-send with icon to Linux from Python, but when I do it from PyCharm's Terminal or from subprocess.run(command, shell=True) with Python, I get an empty icon instead of my icon.

It works when I run it from Linux (being in the same directory as in PyСharm's terminal).

The icon is located in the ~/PycharmProjects/SomeProject/icons/ directory. So I ran this:

notify-send --urgency normal -i ~/PycharmProjects/SomeProject/icons/someicon.png 'Notification text'

And in Python I do this:

import subprocess

command = "notify-send --urgency normal -i ~/PycharmProjects/SomeProject/icons/someicon.png 'Notification text'"
subprocess.run(command, shell=True)
